SynchroStream: Time-Synchronous IP transmission and playout of audio and or video content

The R&D engineers at WorldCast Systems have been busy on a number of new developments.

SynchroStream Time-Synchronous IP transmission and playout of audio / video content.

SynchroStream is designed to precisely synchronise an FM single frequency network.  External GPS clocking locks all carriers and modulation feeds and ensures a stable, homogeneous RF field. The user defines the desired target latency, the interference zones are optimized with the high-precision fine tuning at the transmitter - 125 nanosecond steps, shifting interference zones by distances of less than 50 meters.

Overview

SynchroStream is APT's new technology for time-synchronous IP transmission and playout of audio/video content.  

Content, such as radio programs broadcast with synchronized transmitters (SFN), be it analog (FM) or digital (DAB+), 
or multiple audio channels building a surround sound image which must be synchronized with high precision.  
APT SynchroStream is a professional solution for synchronized content transmission.

SynchroStream Benefits

Content Time-Synchronization

APT's SynchroStream is the must-have solution for locking content to time over IP transmissions.

Broadcasting networks or surround sound transmissions benefit from the high precision of SynchroStream.The user defines the latency of a transmission, only once, and SynchroStream presents distributed contents at the exact same time.

High Precision Time-Synchronization

When synchronizing audio content, we trim in the range of the speed of sound  in the millisecond range. If you need to synchronize an FM carrier, we work in the range of the speed of light in the microsecond range and below. SynchroStream allows adjustments in the millisecond range, in the microsecond range, down to an eighth of a microsecond, which is 125 nanoseconds.  

SynchroStream is the universal time synchronization solution for all applications.

SynchroStream and Analog SFN

Synchrostream is designed to dramatically reduce the impact of the uncertainties of an analog single frequency network.  

The key to the optimal possible synchronization of modulated FM carriers is the smallest possible granularity of time shifts. With 125 nanosecond steps, SynchroStream offers an unprecedented level of granularity of modulation shifting. Disturbed interference zones in the propagation area can be shifted by distances of less than 50 meters.

Ease of Use

SynchroStream is adjusted and optimized in just two steps.

As the user you define the desired target latency. This is done once in the studio on the content encoder. This, dynamically eliminates all deviations of the IP network. Afterwards the interference zones are optimized with the high-precision fine tuning at the transmitter. Thus, all carriers are in correct time relation to each other. The external GPS clocking locks all carriers and modulation feeds and ensures a stable, homogeneous RF field.
